The'object of my invention is to provide a type-Writer which will be simple and inexpensive in its construction, easily' operated, and

which will produce Writing having perfect alignment. Y

--My invention consists in the combination after fully described.

The main frame of themachine consists of the base-plate A, the longitudinal bars B B',

the standards C C', supporting the said bars, and the cross-bars D D', connecting the longitudinal bars B B at the ends of the frame. The standards C support a cylindrical rod E, which forms a guide for lthe paper-carriage. The side bars B B form a guide forthe typeplate carriage F, the said carriage being furnished with ilanges b c, which extend partly over the upper surfaces of the bars B B'.

To the ends of the type-plate carriage F are fitted slides d, to which are attached the typeplate-carrying brackets a, which are turned inwardly at their lower ends to receive the type-plate G. The type-plate G is secured to the brackets a by screws e.

In the'top of the type-plate carriage F are pivoted iwo similar1 levers f f which engage each other at the center of the carriage, and which also engage the slides d and brackets a, so as to cause the said slides to move in unison.

' To the type-plate carriage is attached an index g, which moves along the letter-plate h,

attached tothe bar B of the frame, and to the said type-plate carriage F is secured ahandle I, by which it may be moved longitudinally in the frame.

To the base A, at the center of the machine,

ported by the standards n n2, extending up- Wardly from the end bars m m', and the paper-guide o.

In the end pieces m m of the frame of the paper-carriage is j ournaled apaper-feed roller p. To one of the journals'of the said paperfeedroller is attached a miter-Wheel q,-Which is engaged by a miter-Wheel r on the shaft s, journaled in the bracket t, attached to the end piece m' of the paper-carriage frame. To the other journal of the said roller is attached a milled Wheel p2, by which the paper may be rolled through the machine. Upon the said shaft s, near its outer end, is secured a ratchet-wheel u, and upon the shaft outside of the said ratchet-wheel is placed a lever c, which carries a paWl fw, arranged to engage the ratchetwheel u.

In the end pieces m m' of the paper-carriage frame J, and a short distance above the paperguide o, is journaled a rock-shaft o', carrying a spring-metal comb 0.', the teeth of which rest upon the roller p, and to the said shaft o is attached an arm o2, provided at the end thereof with a curved slot, which is adapted to slide over a threaded stud o3, projecting from the side piece m, the said stud o being provided With a nut 04 for clamping the varm o2 in any desired position, the object being to vary the pressure of the comb a upon the -roller p.

To the bar B' atthe rear of the machine is IOO r when the said'key-lever O is depressed.

attached a plate K, provided with ears b', which support the rock-shaft c.

To the rock-shaft c is att-ached the printing-lever L, which reaches over the top of the type-plate G and is provided with a stud d', which is adapted to strike the top of the typeplate G and produce the imp ression of a single letter upon the paper resting on the platen k. The printing-lever L is normally maintained in an elevated position by the spring e', which engages the ears b and the said lever.

In'ears g', projecting downward from th plate K, is pivotcd the registering-lever M, one end of which extends through a loop N, carried by the lever L, the other being provided with a V-shaped edge adapted to engage the serrated lower edge of the ratchet-bar n.

Between ears h', projecting from the bar B', is pivoted a key-lever O, which extends to the cross-bar D and is pressed upward by a spring, i', the upward motion of the said lever being limited by a stop j. To an ear 7c', attached to the bar B', is' pivoted a slotted lever l', to the free end of which is jointed a pawl O, which is adapted to act upon the ratchet-bar n. ing from the side of the key-lever O, enters the slot of the lever Z', so .that when the lever O is depressed in the operation of printing,

-as will be presently described, it iirst causes' the pawl O to engage the ratchet-bar n.

To the key-lever O is attached abar q,which extends down through an aperturein the bar B- in position to engage the printing-lever L, The bar q is provided with a right-angled arm r', which projects over the flange c of the typeplate carriage F, and carries apin in position to enter any one of a series of holes s in the said iiange and cause the type-plate carriage to register, so that the impressions of the letters or characters on the paper will be proplerly arranged with reference to each other.

At the same time the said pin holds the carriage stationary luntil 'the printing is done.

To the side ofthe key-lever O, near its free end, is pivoted a spacing-key O2, which is provided with a downwardly-proj ecting lever' O3, which reaches below the key-lever, and a thumb-piece O4, which extends over the top of the key-lever. The saidv spacing-key O2 4does not interfere with the free action of they key-lever O. The said key-lever O, when depressed, effects the printing and also Y the movement of the paper-carriage; but when the key-'lever O is moved by touching the spacing-key O2 the said spacing-key carries the key-lever O down far enough to move the vpeper-carriage, but not sufficiently to effect the printing, as the ear O3 strikes the frame of'zthe machine and limits the movement of the said lever O. The downward movement of the key-lever O is limited bya spiral cam O5, pivotcd to the bar B of the machineframe and adapted to turn so as to arrest the downward movement of the key-lever sooner A stud p', project-` when the arm u is released from the trip t.

To the bar B of the main frame is attached an angled arm a2, which carries the inking-pad Y b2 in the path of the characters on the typeplate G, so that as the type-plate passes back and forth it receives ink from ythe said pad. The inking-pad b2 is slotted at the center to allow the type to be pushed downward through the said pad and its support upon the paper immediately over the platen 7c.

The operation of my improved type-writer is as follows: The paper being placed between the comb a and the roller p, as shown in Fig. 5, the type-plate carriage 'F is moved backward or forward until the index g is opposite the character to be printed. At the same time it is determined whether the character shall be upper or lower case by the moving of the type-plate G back or forward by means of the handle I. When the character upon the typle-plate is in position for printing, the lever O is depressed, thereby bringing the bar q into contact with the printing-lever L, forcing the stud d downward upon the typeplate, and the said plate, being of elastic material, is pushed downward, so as to cause an impression of the character upon the paper extending across the face of the platen 7c. While the lever O is passing downward, the pawl o engages the ratchet-bar n and moves it forward one notch before the printing is done. At the same time the registering-lever M engages the under side of the ratchet-bar,

rol;

not only `preventing the ratchet-bar and paper-carriage attached thereto from being carried too far, but also holding the paper-carriage in a fixed position during the instant of printing. When the end of a line is reached, the pawl 0' is lifted, the paper-carriage frame J is returned to the point of starting, and the roller p is turned through a part of a revolution by swinging the lever v vA new line is then begun and the operation proceeds as before.

Having thus described my invention, I claim as new and desire t-o secure by Letters Patentl.
